Question

What is the value of the x variable in the solution to the following system of equations?
4x + y = 8
x − 2y = 2

Answer 1

4x + y = 8-------------- (A)
x − 2y = 2 -------------- (B)

2*A+B


8x +2 y = 16
+
x − 2y = 2
------------
9x=18
x=2

put x=2 in A
4*2+y=8
y=8-8
y=0

Answer 2

ist u have to make the x or y value the same but with different signs (negative and positive). once u have done u cross out the same numbers, then u will be left with 2 like terms, u add them and also add the other side. simplify now. whatever is you value for x or y is, pick one of the equations above then substitute that value in to find the other one.

Answer 3

i have the answer its 2 but i need the work

Answer 4

ok. then what is your new equation since u made one of the x or y value the same

Answer 5

What is the value of the x variable in the solution to the following system of equations?

4x − 3y = 3
5x − 4y = 3

Answer 6

is your answer for x or y

Answer 7

x

Answer 8

pick one of the equation to find the y value. pick any

Answer 9

4*(4x − 3y = 3) = = 16x-12y=12-----------A
3*(5x − 4y = 3) = = 15x-12y=9-----------B

A-B

16x-12y=12
-
15x-12y=9
---------------
x=3
